    • A valve system for a trigger sprayer including a valve forming an air spring with a portion of the trigger sprayer and being made of a flexible or elastomeric material. The trigger sprayer may include an air-spring valve system wherein the air-spring valve system provides precompression during a pump stroke. The precompression forces developed in the valve system during a pump stroke may originate from an air valve or air pocket trapped between a portion of a valve body and a part of the valve system. For example, a valve may be inserted in a tube retainer which is connected to a valve body of a trigger sprayer. Air trapped in a chamber or space between a portion of the valve and the tube retainer may provide a force against the valve such that a certain force must be applied to the valve before it allows product to be released.
    • 一种用于触发式喷雾器的阀门系统,其包括形成具有触发式喷雾器的一部分并由柔性或弹性体材料制成的空气弹簧的阀。 触发式喷雾器可以包括空气弹簧阀系统,其中空气弹簧阀系统在泵冲程期间提供预压缩。 在泵冲程期间在阀系统中产生的预压力可以源于被截留在阀体的一部分和阀系统的一部分之间的空气阀或气袋。 例如,阀可以插入连接到扳机喷雾器的阀体的管保持器中。 被捕获在阀的一部分和管保持器之间的室或空间中的空气可以提供抵抗阀的力,使得在允许产品被释放之前必须施加一定的力到阀。
